Back in control: making savings with BMS optimisation

The optimisation of HVAC controls for a Croydon office has reduced energy use by 28% over nine months, resulting in a £171,000 saving in operational energy costs. REsustain’s Annie Marston describes how CO2 was slashed for a minimal capital cost

The big picture: embodied energy at 100 Gray’s Inn Road

With a new development at 100 Gray’s Inn Road, in central London, set to become the UK’s largest full-timber, net zero carbon office building, Phil Lattimore finds out how the building’s whole life-cycle carbon impact has been assessed

Clear decisions: whole life carbon for façades

By applying the CWCT embodied carbon calculation methodology to a Croydon office, Patrick Ryan Associates estimated whether selecting a new high-performing façade is better for reducing whole life carbon than retaining elements of the original. Anri Doda and Jill Wang explain

Circular route: New Street station lighting retrofit

To minimise embodied carbon in the retrofitting of nearly 900 luminaires at Birmingham’s New Street station, Q Sustain used CIBSE TM65 to calculate the potential savings of reusing existing luminaires. The firm’s Lovely Chavan and Yara Bekdache explain how it saved more than 163 tonnes of embodied carbon

Measuring up for net zero: interview with David Partridge

As one of the most prominent figures in property, David Partridge is in an ideal position to oversee the governance of the Net Zero Carbon Buildings Standard and ensure a definition for net zero is embraced by those who develop, own and build real estate. Alex Smith reports

Facing up to embodied carbon in façades

Façades account for up to 30% of a building’s embodied carbon, which is why the Centre for Window and Cladding Technology is working to produce a new methodology to bring consistency to life-cycle assessments. Buro Happold’s Teni Ladipo reports
